Fig. 2From: Computational modeling of bone fracture non-unions: four clinically relevant case studiesSchematic representation of the four different causes of non-union. I non-union induced by reaming of the marrow canal and periosteal stripping, II non-union due to a critical size defect, III non-union due to a genetic disorder, i.e. NF1 related congenital pseudarthrosis of the tibia and IV non-union due to mechanical overloadBack to article page
